CTGradient

CTGradient is an interface to Core Graphic’s CGShading. It takes care of all the background work that you normally have to do when using CG(anything).

In my case, CTGradient has (in all the cases I can think of) trivialized the drawing of gradients in Cocoa. And I’ll say that’s a good thing, especially when you see how well gradients spice up an interface and with the new resolution independence work going on I’ll venture to say you’ll be seeing them more often than not.
